"This came after a two-hour Dolphins practice Wednesday in another late-August sun. Reggie Bush, still sweating, stayed on the field, the only player to do so.

The other Dolphins moved from the heat to the locker room. Bush caught footballs flung from a machine, fastball-style, depositing each one in a large trash can after the catch. After filling two trash cans, he moved to a side field and began running 30-yard sprints. One after another after another.

Teammate Vontae Davis, finished with an interview, watched a few seconds before shaking his head, saying, "Man," and continuing to the locker room. Reporters debated whether Bush would go to the blocking sled, because that's often a preferred stop.

This, then, has become the surprise of the Dolphins preseason. Jimmy Wilson looks like a seventh-round gem. Charles Clay might grow into a role. Brian Daboll's offense offers to make a flat world round."
